PowerCompass Part Selector
I'm gonna switch over to the parts selector, which is the simpler part of the tool. So I'm gonna click on that and what it brings you over to is a page here in Excel that shows a lot of the Intersil parts and different topologies. But up here at the top, you'll notice there's a selection where you can select a "Competitor Part."
So from this list you can go "manual input," which would allow you to enter your parameters yourself, or you can select an actual device from the drop-down and that will load up that part's parameters and then it will find the closest Intersil device to those parameters. So I'll just give an example. I'll just click on one here. So it loaded up this AD5973 Buck Integrated FET, and you can see the parameters for that. And then what it did is it started looking for solutions that matched or bettered those parameters. So you can see the 85403 is the top device that is closest to the specifications or better. And what it does is it breaks it out color-coded. Green is it meets or exceeds specification, the light-ish green color is it's near the specification but it doesn't quite meet it, and then the orange slash is it does not meet specification. And in the reference to a current, when it doesn't meet specification, it also could mean it is overspecified. So by default if we're looking for a one amp device then up to a two amp device, two times that value is acceptable. So if it was suggesting a three amp device, then we would not color-code that as being green. We would color-code that as being orange because you wanna stick to something that's close to the actual specifications that you're requiring, and not too far over-spec the device.
So that's a basis of how this tool works. Like I say, from here you can go to "manual input" if actually your part wasn't in this long list of parts here. You could come up here and you could go to "manual input." That would allow you to enter your parameters. It would suggest a topology based on your input parameters, and then you would select a topology that you wanted and "show results," which would bring you back to this parts selector with your parameters entered and the closest device to meeting those parameters.
